Function: Equipped with auto-start function. No need to bother rotating the ball with a string.
・"Arm strength muscle training equipment" The balanced, smooth rotation with little vibration and quiet operation is recommended for those who want high-quality items, serious trainers, rehabilitation, and gifts.
・Includes storage bag
・"Train wrists, fingers, and arms" A rotation speed of 8000rpm can apply a load equivalent to 14Kg.
The higher the rotation speed, the more force is required, making it a very effective snap ball as an exercise tool for increasing strength in the wrists, arms, and fingers.
・"Lighter than dumbbells, easy to adjust load" Utilizing the principle of a gyroscope, the load on the arm can be easily adjusted by changing the applied force, allowing you to train with a load that suits you.
・"Exercise equipment for home use" (1) Auto-start: Rotate the rotor by about 2-3 turns in the direction of the arrow with your thumb, and when you release it, the internal rotor will automatically start rotating.
(2) Increase rotation speed: Swing your wrist in conjunction with the rotor.
(3) Centrifugal force and inertia: Move your wrist further to increase rotation speed.
Training begins when you hear an acceleration sound like a sports car.
・"Easy to carry" Weighs only about 254g and is about the size of a baseball.
It is easy to carry, making it much safer, more enjoyable, and more efficient to train with than using heavy equipment like dumbbells.
・Maximum load: 30000RPM
・Size: 7cm x 7cm x 5cm
・Quiet operation OK
・Includes strap
